Application filed May 18, 1912. Serial No. 698.269.

To all ltr/1.0721 it may concern.'

Be it known that I, ALEXANDER VVINTON, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Gas-Engines, of which the following is a speeication, reference being had therein to the accompanying drawing.

My invention relates to improvements in gas engines.

Y The object of my invention is to provide an engine of this character in which the cylinders are cast in pairs with the intake and exhaust passages as a part of the casti ings, and when bolted together the said passages forming the exhaust and intake manifolds with the mixing device or carbureter connected at one end and the exhaust at the opposite end, whereby a block or one unit engine is produced without the disadvantages heretofore found therein.

Another object of my invention is to provide an engine in which the intake and exhaust manifolds are side by side with the water-cooling system between the same whereby the charge is heated, yet there is no liability of the charge being ignited.

A still further object of my invention is to provide a simple, cheap and effective engine having certain details of structure hereinafter fully set forth.

in the accompanying drawings: Figure 1 is a side elevation partly in section of a gas a,- engine embodying my invention. Fig. 2 is a vertical sectional view taken on the line 1.1 of Fig. 1. Fig. 3 is a vertical sectional view showing how the exhaust enters the exhaust manifold.

Referring now to the drawings, 1, 2 and 3 represent the three castings, each having 'two cylinders and thus my improved engine is a six cylinder engine, while it is understood that any desired number of castings may be used to make a four or more cylinder engine. The said castings areconnested together by blocks 4, which are proded with any desired packing for forming a tight joint with the cylinders, and said blocks having openings 41 4.2 to correspond with the openings in the cylinder castings as will be hereinafter more fully described.

The crank case is closed by the plates 5 and 6 and having openings closed by the Specication of Letters Patent.

doors 7, whereby access may be readily had to the cranks of the engine.

The upper ends of the cylinder castings have cast integral therewith housings 6,-

which extend across the cylinder castings and form the intake and the exhaust manifolds, which we will The housings 6 formed integral with the cylinder castings are provided with central exhaust passages 7, horizontally arranged and having open ends which communicate with the openings 42 in the blocks 4. The said passages are surrounded by a space 8, which is in communication with the water-supply of the water circulating cooling system of its respective cylinder. The housings above the water space 8 are provided with transverse passages 9, forming the intake for the gas of the engine, and which communicate with each other through the openings 4 in the blocks 4f.

The upper ends of the cylinders are open and have spaces 9 across the upper end which communicate with the intake passages 9. The ends of the castings are closed by the heads 12, 13 and 14, which are of a hollow form and which are in communication with the water-cooling system of the engine. The said heads are provided at one side with passages 15, which are connected together by the two pipes 16 and 17. The end head 14 has the water supply pipe 18 communicating with the passage l5 therein, while the opposite end of the passage l5 of the head 12 is closed by the plug 15. Each passage of the head has two openings 20 communicating with the water circulation of its respective cylinder in the head and said openings are controlled by the Valves 21. By this arrangement it will be seen that the desired amount of water is allowed to pass to each cylinder. The exhaust passage is also in communication with the space 9 by means of the passage 22, which extends through the intake passage 9. Surrounding the upper end of the passage 9 are valve seats 23, upon which are seated the valves having operating rods extending into the crank case and operated by cams, as is well understood. The space 9', as heretofore stated, communicates with the ends of the cylinders and is therefore a passage for both the intake and the exhaust. The Water circulation of each cylinder is in communication with the pipe 26, which extends along now proceed to describe.

' ing between the exhaust and the intake will heat the intake and cause a better combustion of the fuel and at the same time prevent any liability of it becoming heated to such an extent that it will become ignited.

The end of the exhaust passage 7 is in communication with the exhaust pipe 27,-

which is at one end of the engine, while the intake passage 9 has connected at the opposite end of the engine .a pipe 9', which is in communication with the carbureter.

The housings 6 of each casting Vhave their outer faces provided with openings covered by plates 28, whereby access may be readily had to the spaces 8 surrounding the exhaust manifolds -7, for the 'purpose of cleaning or removing any deposit that may take place in the said spaces.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: 4 v

1. A gas engine, comprising cast cylinders joined together with blocks, and said castings having housings forming the exhausts and inlets and connected by said blocks.

2. A gas engine, comprising cast cylinders joined together with blocks and said casting having a housing forming exhausts and inlets with the water circulation of the cylinder separating the same, and said inlets and exhausts communicated by the blocks.

3. A gas engine, comprising cast cylinders joined together by blocks and said castings having housings formed integral therewith and between which the blocks extend, said housings having intake passages at their upper end and exhaust passages in their lower end communicating with the exhaust passages of the other cylinder through the blocks and the exhaust vpassages communi eating with the ends of the cylinders.

4. A gas engine comprising cast cylinders having exhaust and intake manifolds formed integral therewith, and blocks between the ,cylinders and having passages communicating the exhaust and intake manifolds of the castings.

y5. A gas engine comprising cast cylinders having housings formed integral therewith, said housings having exhaust manifolds adjacent their lower ends, and intake manifolds adjacent their upper end and separated from the exhaust manifold by the water cooling system of the cylinders, said manifolds being connected with tlie upper ends -of the cylinders through separate passages.

6. A gas engine comprising cylinders cast in pairs and having housings formed intevcylinders and having intake and exhaust manifolds extending horizontally therethrough, blocks between the cylinders and having openings connecting the intake and the exhaust manifolds of the castings, cylinder heads closing the ends of the casting and 'having water supply passages therein and Valves controlling the supply of water from said passages to the head, whereby the water cooling system of each cylinderl is supplied with the desired amount of water.

8. A gas engine, comprising cylinders cast in pairs and having open ended housings cast therewith and when bolted together form the intake and exhaust manifolds for the engine, an exhaust pipe connected to the exhaust manifold at one end of the engine and a gas supply connected to the intakeinanifold at the opposite end ofthe cylinder.

9. A gas engine comprising cylinders cast in pairs and having housings cast therewith with exhaust and intake passages and blocks between the cylinder castings and having passagesl communicating with the passages in the cylinder castingsand when bolted together forming exhaust and intake manifolds.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
